Title: Improvements in cushion shoes
IPC: A43B13/18
Filed: 1935-10-02
Abstract: 465,519. Welted boots etc.; cushioning- devices. EVERSTON, J. H. Oct. 2, 1935, No. 27196. [Class 17 (ii)] A cushion plug 18 is inserted in a sharpedged aperture 16 cut in the outer sole under the heel bone to supplement the cushioning effect upon the heel of a cushion filler 15 between the inner and outer soles. The heel sinks into the cushioned area and forward sliding movement of the foot is resisted. The resistance to forward sliding movement of the foot may be increased by incorporating in the forward heel seat portion of the footwear an elevating wedge 22 of leather or other material, which, as shown, may be secured in the forward side of the aperture 16. Alternatively, a wedge member may be placed between the outersole and heel at the breast face, the outersole being slit to assist in its deformation. The cushion plug may have a peripheral flange extending on its underside between the heel and outersole of the shoe. That portion of the filler which lies outside the outline of a normal healthy foot is of less elastic material than that which underlies the foot. A fillet strip of leather or rubber of triangular cross-section may be placed inside the inseam ridge to prevent the margins of the filler 15 from being too clearly apparent to the foot. U.S.A. Specification 2,001,821 is referred to. Reference has been directed by the Comptroller to U.S.A. Specifications 1,968,290 and 1,973,105.

Filed: 1932-10-03
Abstract: Pieces of hard sintered composition consisting mainly of tungsten carbide or other refractory metal carbide are reshaped by heating to or above sintering temperature and pressing, for instance, as described in Specification 289,477, [Class 39 (iii), Heating by electricity].  The heat may be applied through the plungers or at right angles to the pressure as described in Specification 293,864, [Class 39 (i), Electric lamps, Arc &c.].  A pressure of 200 pounds per square inch may be applied during heating, but this is increased to 2000 pounds when the sintering temperature, usually 1350-1425 DEG C., is reached.  The method is useful in salvaging worn or broken turning tools, cutting, forming and bending dies, &c. which may be further broken to insert the pieces into the mould.  If the tungsten carbide contains cobalt a small quantity of powdered tungsten carbide and cobalt may be added.  The method may be used in forming elongated bodies which cannot be formed directly from powder owing to binding against the mould sides.  A worn article, e.g. sand-blast nozzle, may be renewed by pressing with additional powder in a mould of the original form.

Abstract: 1,059,477. Tape handling apparatus. RADIO CORPORATION OF AMERICA. July 3, 1964 [Aug. 13, 1963], No. 27623/64. Heading G5R. Tape handling apparatus for a magnetic tape including a head 24, capstans 26, 28 and supply and take-up reels 16, 18 is provided with main vacuum receptacles 34, 36 forming tape loops 42, 44 and auxiliary vacuum receptacles 38, 40 having tapered sides which form further smaller tape loops 46, 48. These further loops reduce inertial effects on stopping, starting and reversing. Capstans 26, 28 are continually rotating in opposite directions for forward and reverse drive. When no drive is required, the tape is held clear of the capstans by compressed air, and is held stationary to the guide block 106, by transverse grooves from which the air may be exhausted. These grooves also provide transverse rigidity of the tape. In order to drive the tape, vacuum is applied to the appropriate capstan wheel instead of compressed air, and the tape loops in the auxiliary receptacles change their lengths as the tape starts to move. The force on the tape loops in these auxiliary receptacles varies with the loop size, so that when running the loops take up an equilibrium position giving constant tension. The reels 16, 18 are controlled by sensing means associated with the loops in the main receptacles.

Filed: 1927-10-18
Abstract: 302,759. Holzverkohlungs-Industrie Akt.-Ges., and Roka, K. Oct. 18, 1927. Aliphatic ketones; acetone.-Aliphatic ketones are made from primary aliphatic alcohols with two or more carbon atoms in the molecule, such as ethyl alcohol, the aldehyde or aliphatic ester derivatives of these alcohols, or from mixtures of these materials with one another or with other derivatives of the alcohols, such as acetic acid or with inert substance by treating the initial materials with water vapour at a raised temperature, preferably 250-650‹ C., in the presence of catalysts consisting of oxygen compounds of the heavy metals, particularly oxides or substances giving rise thereto; a heavy metal is defined as a metal having a specific gravity greater than 5.5. Promoters may be used in intimate admixture with the catalysts, suitable promoters being oxygen compounds of calcium and magnesium and also metals such as iron. Iron shavings, or porous iron, superficially oxidized and with a promoter, such as calcium carbonate, deposited thereon form a suitable contact mass. The catalysts may be activated by treatment at a raised temperature with oxygen or oxygen-containing gases, and it is preferred to activate the catalysts at short intervals. Small amounts of oxygen or oxygen-containing gases may also be introduced with the reaction mixture for this purpose. In making acetone from acetaldehyde, however, it is sufficient to interrupt the supply of acetaldehyde from time to time, and to activate the catalyst by treament at 450-600‹ C. with steam alone. The hydrogen produced in the process may be used to heat the reaction chamber either externally or, if air is admitted with the reagents, internally. In one example, acetaldehyde and water vapours are passed at 490‹ C. over a contact mass prepared by immersing rusty iron shavings into calcium acetate solution, evaporating the solution, and heating the product; acetone is obtained. In other examples mixtures of water vapour with the vapours of ethyl alcohol and ethyl acetate are passed at 500‹ C. and 510‹ C. respectively over the same contact mass as in the first example; acetone is obtained in each case.
